Hi I've been trying to get image tracking running on my android device however when I build and run the apk all I get is a blank screen. The sample scenes also show up blank. I'm enabling app permissions to the camera and storage and have tried running with and without the Camera2 Api being enabled.

Hello Matthew,

Which mobile device are you testing with? Does this happen with our sample app as well or with your own app?

Hi Eva,

Thanks for the reply. I'm using a Moto G5. The Unity examples app works fine. It occurs when I import the package into a new project both my app and the sample scenes included do not work and show a blank screen instead of the camera view.

Thanks,

Matt

Hello,

I have the same problem when running the wikitude example Instant Tracking - Scene Picking using a Samsung Galaxy S8 or a Lenovo Phab Pro 2.

Hi,

Yes there are quite a lot of error messages coming from android monitor, I hope this helps.

It seems that Multithreaded Rendering is the cause for this issue. Until we find why this is not working, please disable it from Player Settings -> Other Settings tab.

Best regards,

Hi,

We're working on adding support for that and it will be available in the next version of the SDK.

I just loaded the newest SDK (7.2 Unity) and experienced the same issue. Looking forward to the next version!

Hi John,

Multithreaded Rendering is not yet supported in our current release (so that would be 7.2), but is already included in our upcoming release. So stay tuned to find out when it will be available (we will mark this forum post as solved properly ;) and in the meantime, as Alexandru suggested, please disable it from Player Settings -> Other Settings tab.

Thanks

Eva

Understood, already did!
It's resolved in the sense that the original person found a fix, I was keying on the point that the multithreaded rendering fix isn't in place yet. No worries! Sorry to be so terse.
Thanks.
